4-Methoxybenzoyl chloride

Methyl l-Methoxyltellurobenzoate)1 A solution of 0.171 g (1 mmol) 2-methoxybenzoyl chloride in 8 ml tetrahydrofuran is added to 0.174 g (1 mmol) of freshly prepared sodium telluride (liquid ammonia method). The mixture is stirred at 0° for 1 h and then filtered. The solvent is evaporated from the filtrate under reduced pressure. The red, oily residue is cooled to — 63° under nitrogen and mixed with 2 ml (32 mmol) iodomethane. The mixture is warmed to — 30° and stirred at this temperature for 2 h. The excess iodomethane is evaporated under reduced pressure below 0°. The residue is treated with 5 ml dichloromethane, the black mixture is filtered, and the filtrate evaporated under reduced pressure below 0° to give yellow crystals yield 84% m.p. 25°. 

Sodium 2-Methoxybenzenetcllurolocarboxylate A solution of 0.171 g of 2-methoxybenzoyl chloride (1 mmol) in 8 ml of tetrahydrofuran is added to 0.174 g of freshly prepared disodiura telluride (1 mmol). The mixture is stirred under an atmosphere of nitrogen at 0° for 1 h, then filtered, and the filtrate kept under reduced pressure to remove the solvent. The produet remains as a dark-red oil.

Also obtained by degradation of 6-chloro-2,3-diphenylbenzofuran with chro-minm trioxide in boiling acetic acid during 40 min or 2 h, followed by saponification of the 2-benzoyloxy-4-chloro-benzophenone so formed with 2 N or 4 N sodium hydroxide in refluxing aqueous ethanol for 1 h or 15 min [44,515]. Preparation by reaction of 4-chloro-2-methoxybenzoyl chloride (SM) with benzene in the presence of aluminium chloride at r.t. [6] according to [14]. SM was obtained from 2-amino-4-chlorotoluene by a four-step synthesis. 

Also obtained by reaction of 2-methoxybenzoyl chloride with toluene in the presence of aluminium chloride [5,9], (72%) [13], (47%) [17].
